for everybody that is using offset shackles

It depends on which shackles you use. The MP offset shackles are .8" offset. Others are .5 (1/2"). That's why I always stuck with the MP.

I have the mopar ones , I guess, installed them and ordered a dana 60 w/ detroit locker , set up for the offset kit , ""3/4'' , dropped right in perfectly and been in there for 10ish yrs . !!
